Fix bug that made changes to a special remote sometimes be missed when
importing a tree from it. The diff import would miss when a change was
exported, then manually undone on the special remote (eg deleting a newly
exported file). A full import is needed to catch such changes.
After upgrading, any such missed changes will be included in the next
tree imported from a special remote. This happens because the previously
recorded content identifier tree does not have export information included,
so it is treated as invalid, and a full import is done.
Fixes reversion introduced in version 10.20230626, commit
40017089f2
Unfortunately, this does mean that after each export, the next import will
be a full import. Which can take significantly longer than the diff import
does, when there are a lot of files in the tree.
It would be better if exporting also update the content identifier tree.
However, I don't know if that can be done inexpensively. It would be future
optimisation work, in any case.
(That could only be done for an export that is run in the same
repository as the import. When an export is run in a different repository,
the export.log gets updated, and that propagates to the repository where
import is later run. At that point, a full import is done.)

enableremote with the same type= as initremote had before might be worth
allowing, but I'll wait and see if someone else complains
Fix hang that could occur when using git-annex adjust on a branch with a
number of files greater than annex.queuesize. Or potentially other
commands.
When reconcileStaged is running, the database is being opened. But
restagePointerFiles closes the database, and later writes to it. So it will
deadlock if called by reconcileStaged.
The deadlock occurred when the git queue happened to be full, causing
adding a call to restagePointerFiles to it to flush the queue and
restagePointerFiles to run at the wrong time.
Fixed by making reconcileStaged, when it populates or depopulates a pointer
file, arrange for restagePointerFiles to be run as a cleanup action, rather
than from the git queue.
But, what if restagePointerFiles is already in the git queue before
reconcileStaged is run? If it adds anything else to the git queue, causing
the queue to flush, it would still deadlock. To avoid this hypothetical
situation, added a Annex.inreconcilestaged, and made restagePointerFiles
check it and not do anything.
Note that, I did consider the simpler approach of only running
restagePointerFiles as a cleanup action, rather than from the git queue.
But see commit 6a3bd283b8 for why it was made
to use the queue in the first place. I wanted to avoid tying this bug fix
to a behavior change.

Changing the type out from under an existing special remote exposes the
existing config to something that may interpret it wildly differently. As
seen in the bug report, this can even result in behavior that makes
git-annex say it's buggy. So prevent the user from doing this. --sameas is
the better way.
